This is a topo map of exactly where the Basic Training area is located. Note that the trailhead for Blackrock trails is down by where it says "Camp Tapawingo" and the top of the trail system is up off the map just a bit (somewhere around 2,000 feet at top of Mt Brown). the roads are used for part of trailsystem, but mostly the trails are off into the trees...(and sometimes UP into the trees!)
